I did a 2 hour ride and experimented with the Scala Rider G9 turned off and the Montana functioned perfectly. As soon as I turned the Scala Rider on, the Montana GPS acted up with poor tracking, incorrect navigation and Loss of satellite reception. I also gave a go at (i) having the Bluetooth function on my phone turned off and (ii) the phone itself turned off with the Scala Rider left on in the previous two scenarios, but the GPS still acted up in these circumstances.

Unfortunately, I have to assume the Scala Rider G9 and Montana 650t are incompatible in my setup?

Did you try a different G9 in your setup to see if yours is wonky?

Have you contacted Scala? Hope you don't mind, I posted your observation to the Scala Facebook page to see if others have heard of or experienced it.

"The motorcycle, being poorly designed for both flight and marine operation, sustained significant external and internal damage," police noted.

I can easily try the other G9 that came in the set I purchased. I will plan on doing that to see if there is any difference.

Thanks for posting my dilema on the Facebook page. I don't use Facebook, so if you get any noteworthy feedback, letting me know would be great.

I did a couple google searches on the isuue, but came up empty.

I have sent an e-mail to Cardo systems and will post the results when received.

Appreciate the Interest,
Glenn

I'll let you know if I hear back from them, or anyone else, through FB.

I obtained another Montana 650t and tried it, with no difference in the performance.

I switched the Scala Rider G9 for another unit (my wife's paired G9) and no difference.

I contacted Cardo Systems via e-mail and I doubt they read my message as they replied with regards to Bluetooth functionality in their message, so I'm not impressed that they didn't bother to properly read my message and respond appropriately.

Contacted Cardo via telephone and explained my problem, but the only thing he could offer was to make sure the "click to link" was turned off. When I checked on this it was "off".

So for me, in my experience, the Scala Rider G9 is not compatible with the Garmin Montana 650t because of some type of interference with the Montana GPS satellite signal causing poor tracking and eventual loss of satellite reception with prolonged intervals before any sort of satellite reception is re-established. As such, I cannot recommend the Scala Rider G9 to be used with the Garmin Montana 6xx series GPS

Anyone using a Sena SMH10 successfully with a Garmin Montana 6xx series?

Interesting that Scala cares so much about it. For the record, our pair of G4s work just fine.

Never did hear back on Facebook, except for a generic "Contact Help" message from Scala.

Maybe you'll get more feedback if you post in the main Montana thread?

Glad to hear your G4's work perfectly.
I did ask what the difference between the G9 and G4 was, as you had mentioned previously that the G4's worked with the Montana, but the response was mainly the difference in the "click to link" allowing a greater number of riders to communicate.

could it just similar to the emf interfrence that another user had and solved by using a "choke".Hope i have the terminolgy right

I was reading through this post, but have neither the Scala or a Montana GPS on my bike. The idea of a choke is a good one. I found that it helped me in previous setups on my Dakar and a GPS system.

If you have a friend who is an amateur radio operator "ham", ask him for a type 34 snap-on type ferrite bead or two. Wrap any wires leading into the Scala and the Montana in them, snap them shut, and see what happens. Sometimes any wires running into units like these act as antennas and can pick up unwanted signals that will screw up the unit. hope this helps.

Its very common for electronic devices - especially ones that use any type of wireless technology or antennas to interfere with each other.

The fix is simple - just move them to either side of the handlebars.

The Scala radio in this case is already up on the riders helmet. Some distance from the Montana.

I have been using a SMH10 & SMH10R with my 650 on rugged mount that is connected to SM10 and no problems.

Thanks for this. A neat looking setup.
How did you find the security of the mounting for the battery and unit?

Not sure if your asking about the SENA system or the Montana. But I had no issues with either Sena systems on the 1150GSA or the SMH10R mounted on my Neotec helmet in the 6,000kls we did.

The Montana I have had 1 year & have had no issues with the battery, but then I did the ear plug on the battery from the start.

Only issue I have is the security screw on the rugged mount failed this trip, so I'll be doing the fix mentioned here some weeks ago. Might even do the rugged mount on the LT that way I can save some weight & not have to carry the Garmin Special Screw Driver .

Where would the "choke" be placed? The intercomm system is self contained unit and operates with Bluetooth tecnology. The GPS unit is self contained unit as well, but it does have a 12 volt power wire. Would there be any advantage to installing a "choke" on the 12 volt wire? Also by "choking" out some RF waves, would I be decreasing the effectiveness of either the intercomm or the GPS? Sorry for my ignorance here.
